UCLA scientists develop PP405, a new molecule showing promise in treating hair loss.

Scientists at UCLA have developed a new molecule called PP405 that shows promising results in treating hair loss. In clinical trials, PP405, when applied to the scalp, significantly promotes the growth of full hair rather than fine "peach fuzz." This new treatment is seen as a breakthrough because it can potentially work alongside other therapies. Current FDA-approved treatments include minoxidil and finasteride, but PP405 offers a different mechanism that could lead to more effective hair restoration.
